ADM666AN-IC
The ADM663/ADM666 precision voltage regulators feature a maximum quiescent current of 12 mA. They can be used to give a fixed +5 V output with no additional external components or can be adjusted from 1.3 V to 16 V using two external resistors. Fixed or adjustable operation is automatically selected via the VSET input. Low quiescent current makes these devices ideal for battery-powered systems. The input voltage range is 2 V to 16.5 V and the output current can be supplied up to 40 mA. The ADM663 can directly drive an external current in excess of 40 mA through the transistor. Additional features include current limit and low power shutdown. Thermal shutdown circuitry also includes additional safety. The ADM666 features an additional low battery monitoring low battery voltage detection circuit. The ADM663/ADM666 are pin-compatible replacements for the MAX663/666. Both are available in 8-pin DIP and in a narrow surface mount package (SOIC) package.
